Some statistics about all robotic #LunarLanding attempts so far from 1965 to 2025 compiled from en.wikipedia.org/wiki/List_of_ and scicomm.xyz/@AkaSci@fosstodon. in which I only count those for which descent to the surface had been initiated, not missions lost at launch or on the way - in a nutshell ~70% of all landings by government agencies went well (essentially the same rate 60 years ago and now!) but only ~30% by private companies. Here goes ...
There have been two separate periods of soft lunar landing attempts of ca. a dozen years each, from 1965 to 1976 and 2013 to 2025 (ongoing) with a huge gap between them.
In the first interval there were 20 attempts with 13 successes (Luna 9, 13, 16, 17, 19, 20, 21 and 24 and Surveyor 1, 3, 5, 6 and 7), one partial success (Luna 23, counting as 50%) and 6 failures (Luna 5, 7, 8, 15 and 18 and Surveyor 4), so the success rate was 13.5/20 = 68 %. All missions were by - the Soviet and U.S. - governments.
In the second interval there were so far 14 attempts with 6 full successes (Chang'e-3, 4, 5 and 6, Vikram 2 and Blue Ghost), three partial successes (SLIM, IM-1 and 2, counting as 75%, 50% and 25%, respectively) and 5 failures (Beresheet, Vikram 1, Hakuto-R 1 and 2 and Luna 25) so the success rate was 7.5 / 14 = 54%.
But looking only at the government missions it was 72%, slighly up from 50 years ago. While for the commercial attempts it was only 29%. In total the success rate was 19 (18 government-run) missions out of 34 (28) attempts or 62% but 69% for governments only. And if you throw in the 6 Apollo landings, the total success rate rises to 68% and the government-only rate goes even up to 75%.

50 years of reunification, the end of the second Indochina war, #Vietnam had a blast with a mammoth celebration. The nationalism is troubled but it goes strong. An entire day of a parade in Saigon and on TV, and we had a tank in the newspaper 🤷
Interesting, since it’s the final days abroad for us

Lots of tiny red Vietnam flags lined up across a tree, blue sky avoce and curbside below
A cardboard build your own tank as part of the newspaper. A gift to readers, all under the header of 50 years of glory, the propaganda of the government. The longer you read about propaganda propaganda, the less dramatic it sounds. But lest not forget that this was a civil war and that there's a history with a yellow flag, communities still strong, e.g., in the US

This was June 7, 2014, so 11 years ago. For some people, in IT everything older then 10 years already counts as vintage.

"As the West debates red lines and escalation risks, Ukraine’s spies are doing what no NATO agency dared: hunting Russian war criminals across three continents, from Moscow’s suburbs to Mali’s deserts — the very territories where Russia projected power unopposed for years.
Russia’s failed blitzkrieg birthed something far more dangerous than Ukrainian resistance — Ukrainian revenge."

"It is fair to say that Microsoft spent at least the first five years of its history in relative obscurity. The first appearance of the name “Microsoft” on the pages of Byte was a short mention of their BASIC interpreter in an advertising on page 47 of the May 1977 issue. In contrast, page 34 of the same issue included an article about the Apple II by Steve Wozniak. The Woz and Gary Kildall were the biggest stars of the microcomputer industry at the end of the 1970s."

I'm 37 years old and I finally finished a #JRPG game for the first time in my life ( #SeaOfStars ).
I like them a lot, but I often get bored of the grinding, or I have to leave it for some time and when I come back I don't remember what I was doing.
Why I managed to finish it this time? Because I had more important, stressing and boring things to do instead, and my brain demanded procrastination. #ADHD
